dt (Display Task State Segment)

dt [addr]
 

The dt command displays the current task state segment (TSS) or the selected TSS if you specify the optional address. More information about the TSS can be found in Intel's "Pentium Processor User's Manual, Volume 3" (1993). This command can be useful to view the register state at the time a double-fault occurs (dt 18:0).

addr

Specifies the address of the TSS to display. If no addr is given, dt displays the current TSS pointed to by the TR register.
